samd/machine_uart: Implement a Python UART IRQ handler.
Supported for all SAMD51 devices and SAMD21 with external flash. For
interrupt events, IRQ_RX and IRQ_TXIDLE are provided.
IRQ_RX is called for every received byte. This may not be useful for high
data rates, but can be used to build a wrapper class providing an
IRQ_RXIDLE event or to signal just the first byte of a message.
IRQ_TXIDLE is called only when messages are longer than 5 bytes and
triggers when still 5 bytes are due to be sent.
The SAMD hardware does not support implementing IRQ_RXIDLE.
